Prince William And Harry Admit Regret Over Last Phone Call With Diana

During the 20th year since her death, Princes William and Harry have opened up about the last moments they remember sharing with their beloved mother Diana, for a new ITV documentary, Diana, Our Mother: Her Life And Legacy, airing tonight, Monday 24th July.

The Princes, who before this year have remained relatively silent about their mother, have revealed some deeply personal memories about the former Princess of Wales.

The boys, who were 15 and 12 when their mother passed away, reflect on the very last time they spoke to Princess Diana, over the phone. They had been away from their mother for over a month at that point, and were at the time on holiday in Balmoral with their cousins Zara and Peter Philips, while Diana was in Paris withher companion, Dodi Faye.

Discussing the heartbreak of speaking to their mother for the last time without knowing it, Prince Harry admitted, "I can't necessarily remember what I said, but all I do remember is regretting for the rest of my life how short the phone call was."

Continuing, Harry discussed just how emotionally scarring it's been, knowing that that was the last time he got a chance to speak to his mother.

He said, "If I'd known that that was the last time I was going to speak to my mother, the things I would have said to her," he said. "Looking back at it now - it's incredibly hard. I have to deal with that for the rest of my life: not knowing that it was the last time I'd speak to my mum, how differently that conversation would have panned out if I'd had even the slightest inkling that her life was going to be taken that night."

In the documentary, Prince William also shared his own thoughts on the phone call, saying that at the time, he and Harry were, "running around, minding our own business, playing with our cousins and having a very good time."

And he also admitted that the boys were, like any young kids, in a rush to simply say "goodbye, see you later, can I go off?"

The Duke of Cambridge also shared how, "If I'd known what was going to happen I wouldn't have been quite so blasé about it. That phone call sticks in my mind quite heavily."

The heartbreaking revelations are revealed in a documentary which will celebrate Diana's life and works.

Speaking about the moment they were notified of her sudden death, Prince William also described in the documentary how her passing was like an "earthquake" in the family, sending shockwaves through the lives of both of her sons.

Despite the boys going through such heartache over losing their mother, they remembering Diana is still a positive experience. William admitted that he's been able to feel more comfortable remembering her over time. "There's not many days that go by that I don't think of her, you know - sometimes sad, sometimes very positively.

He continued, "You know, I have a smile every now and again when someone says something and I think that's exactly what she would have said, or she would have enjoyed that comment.

"So they always live with you people you lose like that. And my mother lives with me every day."

The documentary will air at 9pm tonight on ITV.
